COIN-CONTROLLED PUNCHlNG-BAG.

Specification of Letters Patent.

Patented June 5, 1906.

Application filed February 3, 1905. Serial No. 248,954.

Figure 1 is a sectional side elevation of my 1 improved apparatus. Fig. 2 is a cross-section on a larger scale. Fig. 3 is a sectional rear view, and Fig. 4 is a partial vertical sec- }ion, these views being on a larger scale than My-invention relates to the class of coincontrolled punching-bags wherein the bag is automatically withdrawn after the same has been struck to the blow-register.

The object of the inventionis to provide a simple and effective mechanism by which the movement of the bag may be controlled and by which the bag will be withdrawn after the'blow has been struck. It is also designed to automatically drop the bag to strikingposition when the operatorinserts a coin and pushes the'knob.

In the drawings, 2 represents the case'having the overhanging portion 3. To this overhanging portionis'pivoted the shelf 4 by the hinges 5, this shelf being the portion which' is struck by the bagin its upward movement. The bag 6 ishung byfleXible connection, such as a chain 6, upon a'leverarm 7, which is pivoted to a standard 8 and has a rear arm 9, connected by a spring 10 with a vertical link 11. This link extends down through the partition 12, and to its lower end is connected a spring or a weight 13, which acts to nearly counterbalance the weight of the arm 7 and the bag.

T o the intermediate portion of the link 11 is pivoted a catch or trigger 14, having a lower lug 15 arranged to engage thelower edge of a cross-bar 16 when in certain positions. The bar 16 is secured to two depending straps 17, secured to forks 18, projecting from a lever 19, which is pivoted to the shelf 4 at 20 and has a forward-projecting arm 21, which is preferably engaged by the lever 7 when inits lower dotted position. The crossbar 16 and straps 17 are normally held down by springs 22, secured to the partition 12. The slot for the coin leads into a chute 23, which drops the coin into a receiver 24, secured to a slide 25, having a registering slot or hole 26. The bottom of the slot 26 is normally closed by the front end of a lever 27, which is pivoted to the slide by lugs 28, the rear arm 29 of this lever being arranged to rest against the lug 15 when it is raised.

The slide is normally drawn forward by springs and is pushed back against the action of the springs by the projecting'hand knob 31.

When the parts are in'the position shown in full lines in Fig. 1, the coinis dropped into a chute, and as it enters the slot 26 it overbalances the front end-of the lever 27 and throws itsrear arm 29 up into engagement With the latch. The'weight of the coin holds the lever 27 in this position. The operator forces the lower arm of the catch b'ackwardly and releases the cross-head "16. The bag will then descendto striking position, owing to the arm 7 andthe bag being'heavier than the weight 13. As the cross-head rises the lever 27 tilts sufiicientlyto discharge the coin, which drops down into the frontportion-of the case into any suitable'receptacle. When the user then strikes the bag, it will b'e driven up against the pivoted shelf4, and the down ward pull on the supporting cord or chain, together withthe upwardforce of the blow, act-ing upon the lever 19, will pull up the cross-head 16, which had beendrawndown by thesprings 22. A blow upon the bag will cause the cross-head to be drawn up, even if-the bag doesnot strike theshelf'in its up-- ward movement, by reason of'the fact that the strain upon its support will draw the outer end of the supporting-lever 7 downward, thereby depressing the projecting arm 21, to which are attached the depending straps 17 ,carrying the said cross-bar 16. Assoon as the cross-head is drawn up a short distance its lower end will be brought above the catchlug, which will then be snapped into place by a spring 32, bearing against itsupper portion. The bag is thus held in raised position by the action of the springs 22 upon the cross-head and trigger carried on the link. It will be noted that in normal position the bag is not locked in raised position and may be drawn down against the action of the springs. It will, however, at once be drawn upwardly by the springs as soon as the coin is inserted and the knob pushed inward to withdraw the latch from the spring-pressed cross-head.

The blow-recording mechanism comprises a dial on the front of the frame, over which moves a pointer 33 upon a short shaft 34, having secured thereto a pinion 35. A rack 36 meshes with the pinion and is inserted by a hanger 37, secured to a bracket-arm 37, mounted on the shelf 4. This hanger has a bent lower portion provided with a squared or rectangular'slot through which the rack extends. The upper end of the rack is provided with a bumper 38, which normally rests upon the bent portion of the hanger at the side of the hole. The rack therefore hangs loosely and its lower portion is guided by the guide 39. The teeth of the pinion are intermittently engaged by a pivoted trigger 40, the rear arm of which is arranged to be engaged by a projection 41 at the upper end of the latch 14.

When the blow is struck and the bag driven upwardly against the shelf, the pivotal action of the shelf will carry the bracketarm 37 and the hanger 37 upwardly and the blow will cause the rack to move up through the hanger. The amount of this movement will depend upon the force of the blow and the trigger will be moved into engagement with the pinion by the spring 42. The trigger remains in engagement with the pinion, locking the pointer in its registered position until another coin isinserted. When the latch 14 is dropped by the knob and the bag descends, the upper end of the latch then being swung in will strike the trigger and release the pinion as the bag comes down to striking position. When the trigger is released, the pointer returns to zero by gravity. A spring may be used to return the pointer to zero, if desired.

The advantages of my invention result from the simplicity and ease of operation of the device. The bag descends automatically when the coin is inserted and the knob is pushed, thus doing away with the pulling down of the bag and increasing the life of the machine. A blow upon the bag in the present case will cause it to be lifted to inoperative position, no matter in what direction the bag swings. In other words, the downward strain upon the bag-support will cause the mechanism to act even if the bag does not strike the shelf in its upward movement. I thus insure the return movement of the bag after one blow is struck. The locking of the bag in raised position is avoided, thus making the device less complicated and also less liable to get out of order.

Many changes may be made in the form and arrangement of the mechanism without departing from my invention.

I claim 1. In a coin-controlled punching-bag, a release device controlled by a coin and arranged to automatically lower the bag; substantially as described.

2. A coin-controlled punching-bag havin a supporting connection therefor, an automatic return mechanism for the bag, connections for said return mechanism arranged to be actuated by a strain upon the supporting connection, and a bag-release device con trolled by a coin; substantially as described.

inoperative position; substantially as described.

5. A coin-controlled punching-bag having a device arranged to normally hold the bagin raised position, and a coin-controlled release device arranged to automatically lower the bag; substantially as described.

In testimony whereof I have hereunto set my hand.
